[Crash] Dedicated Server with UMG

Hi

Yes it’s occurs on a clean project with no additional content, i found a lot of logs but i only uploaded the last from 2 different project or would you like all the folder ?, maybe you can reproduce it with creating a join/host system blueprint with UMG, and lunch it with dedicated server, the crash happened on 3 different project with the same procedure, i create a lobby system everything work fine without dedicated server, but once i enable it, the crash happen, i hope you’ll find out what’s the matter

Thank you
